Continuing from my earlier post. 3) Printing. (Repeating from my first post) I'm using a MacBook with Leopard on a new 250GB HDD. The printing arrangement stays as it was under Tiger. I have a Brother HL2040 printer (that I call "CarlyPrint") upstairs connected the first model iBook that's running 10.3.9, with printer sharing turned on. This "just worked". I had been printing through this printer from my MacBook and my wife's PowerBook, both running Tiger. And the only thing that's changed is that Leopard is now running on the MacBook. The MacBook no longer finds CarlyPrint. Leopard Help says it (Leopard) can find a shared printer on a local Mac if it's running 10.4 (Tiger) or later. So the working printer sharing arrangement is kaput. Had I known this, it would have been a show-stopper. Two show-stoppers, one annoyance. Now, I have to consider reverting to Tiger, and eBay'ing Leopard. Of course, history says I should wait for 10.5.2. Wish me luck. Jon
